Until this point in history there has been a reasonable correlation between the quality of writing and the "quality" of the underlying work in most text. If effort was put into the writing (and learning to write), that in itself used to be a decent indicator that effort and skill also was put into the data/ideas that the text conveyed.

That rule no longer works. People are still going to rely on it for a while though, and I'm worried it's going to break some stuff over the next few years.
